CARRIER FOR BRAIDlNG-MACHINES.

Specification of Letters Patent.

Patented June 11, 1907.

Application filed July 12,1906- Serial No. 325,796.

' To all whom it may concern:

cage, in the county of (look and State of Illinois, have invented acertain new and useful Improvement in Carriers for BraidingMachines, ofwhich the following is a full, clear,

concise, and exact description.

My invention relates to a spool-carrier for braiding machines, and itsobject is to simplify the construction of the carrier and to provide adevice which will run at a greatly increased speed, and at the same timewill decrease the wear by lessening the tendency of the flange of thecarrier to cramp in the raceway of the machine.

In carriers of well known. construction the slack in the thread is takenup solely by a weight provided for this purpose. In my invention theweight of the cop-holder and the material carried thereby is alsoutilized for controlling the slack, thereby greatly in-. creasing theslack-controlling weightwithou t any increase in the total weight of thecarrier.

In the devices prior to my invention the weightof the cop-holder and thematerial thereon did not serve any useful function, but on'the contraryrendered the carrier topheavy and, owing to the centrifugal force due tothe rapid .mo-vements of the carrier, rendered the guide flange of thecarrier liable to be cramped in the guideway of the machine with whichit was used. Such dead "weight of the copcarrier necessarily keeps downthe speed of the macl'iine.

From experience I have found that carriers of my invention arecapable ofoperation at a speed of approximately 300 revolutions per minute, whereold .types of carriers are capaa vertical section, with parts ,inelevation,

showing the cop-holding slccvein its lowered position; Fig. 3 is adetailed view of one of the parts.

Similar letters of reference are used to designate similar partswherever shown.

The foot 1 of the spool-carr er is provided with the usual guidingflange 2 extending beneath the same. A spindle 3 and a standard 4;extend vertically from the foot 1 and are preferably cast integraltherewitln A sleeve or cop-holder 5 is rotatably mounted on the spindle3, said sleeve being adapted to hold a cop of thread 6 in the usualmanner. The lower end of the sleeve 5 is providedwith a series ofradially projecting lugs 7, adapted to engage a flange 8 on the foot,and thus act as a stop for preventing the rotation of said cop-holder.5, however, has a longitudinal movement on the spindle 3, and the lugs 7may be raised out of engagement with the flange 8 to permit the rotationof the sleeve, as shown in Fig. A washer S) upon the end of the spindle3 limits the upward movement of said sleeve.

A weight 10 is slidably mounted upon the standard 4, said weight andstandard being of the usual well-known construction. A slidable rod 11has a loop 12 at its upperend which engages the standard 4 above theweight 10 and in the path of movement thereof. The lower end of said rodis provided with a foot 13 which straddles the flange 8, said footextending beneath the sleeve The weight 10 in its-extreme upwardmovement thus engages the rod 1], lil ting the same, which in turn liftsthe sleeve 5. The upward movement of the 'rod 11 is limited by a screwor other stop 14 which engages with the foot 13. The upward movement ofsaid rod is sufficient to lift the sleeve 5 until the studs 7 are out ofengage- 1811i? wit-h the flange 8, and the sleeve, therefore, is free torotate.

The thread is led from the cop 6 through a hole 15 in the standard 4,through the weight 10 and out through a hole 16 in the top of thestandard. in a bight formed in the thread between holes :15 and 16, andtends to take up the slack in the thread as the carrier moves in and outin braiding. As is apparent, when the sleeve 5 is lifted its weightsupplements the weight 10, as a slack-controlling weight.

hen there is the proper length of thread to allow the carrier to move inand out in braiding, the weight upon the thread will takeup the slackand hold the thread at a proper tension. Under these conditions thestuds 7 will engage the flange 8 and hold the The weight 10 is thussupported The sleeve I I for taking up slack in the thread fed'from andmeans whereby said sleeve andcop act sleeve from turning When morethread is required the tension of the thread will raise the weight 10,which will lift the rod 11, thereby also lifting sleeve 5 sufficient to5 permit its rotation to let oii more thread.

Under normal operation of the braiding -ma'ch1ne the weight 10 ispressing against the rod 1 1, slightly lifting the same and thus utilzingthe weight of the sleeve 5 and the i0 cop 6 as an "additional slackcontrolling weight. I

Having described my invention, 1 claim: 1. The combination with acop-holder, of means whereby said holder acts as a weight said cop.

2. in a spool-carrier, the combination with a spindle, of a sleeverotatably mounted thereon and adapted to hold a cop of thread,

as a weight for taking up slack in the thread fed from said cop. i

3. The combination with a'copholder, of

a weight for taking up slack formed in the i 2 5 thread fed from thecop, and 'means whereby. the Weight of said copholder supplements theslack-controlling weight.

4. A spool-carriercomprising a hoot havl mg a vertically extendingspindle, a sleeve ll 0 rotatably mounted on said spindle and i1 adaptedto hold a cop of thread, said sleeve having a longitudinal movement onsaid spindle, a stop for preventing the rotation of U said sleeve whenin its lowered position, a slidably mounted weight for taklng up slackin the thread, and a slidable rod extending above said weight andbeneath said sleeve preventing the rotation of'said sleeve when in itslowered position, and means whereby the tension of the thread raises thesleeve free from said stop.

6. A spool-carrier comprising a foot having a standard and a spindle, asleeve rotatably mounted on said spindle and adapted to hold a cop ofthread, said sleeve having a vertical movement on said spindle, studs onsaid spindle, a flange or stop with which said studs are adapted toengage when the sleeve is in its lowered position on the spindle, aweight slid ably mounted upon the standard, and a rod slidably engagingsaid standardv in the path of movement of said weight and extendingbeneath said sleeve for lifting the same free from said stop.
